BEFORE YOU START
WARNING
To avoid possible explosion:
•
Never apply flame or steam to a refrigerant cylinder. If you must heat a cylinder for faster charging, partially immerse it
in warm water.
•
Never fill a cylinder more than 80% full of liquid refrigerant.
•
Never add anything other than R-410A to an R-410A cylinder. R-410A operates at a 50 to 70% higher pressure than
R-22 systems. Service equipment used must be listed or certified for R-410A.
•
Store cylinders in a cool, dry place. Never use a cylinder as a platform or a roller.
WARNING
To avoid possible explosion, use only returnable (not disposable) service cylinders when removing refrigerant from a
system.
•
Ensure the cylinder is free of damage which could lead to a leak or explosion.
•
Ensure the hydrostatic test date does not exceed 5 years.
•
Ensure the pressure rating meets or exceeds 400 pounds.
•
When in doubt, do not use the cylinder.
